File permissions and chflags

Hi

After I completed my first build/installworld and ran mergemaster I now have a directory within /var/tmp called temproot which I am unable to delete.

I thought it must be something to do with the "sticky bit" so ran

chmod 0700 on it

It now looks like this

# ls -lo
total 4
drwx------ 3 root wheel - 512 Oct 28 17:08 temproot
drwxrwxrwt 2 root wheel - 512 Oct 30 23:20 vi.recover

When I try deleting the directory whcih has empty directories within I get this

# rm -rf temproot/
rm: temproot/var/empty: Operation not permitted
rm: temproot/var: Directory not empty
rm: temproot/: Directory not empty

# cd temproot/var

# ls -lo
total 2
dr-xr-xr-x 2 root wheel schg 512 Oct 28 16:27 empty
-bash-2.05b# dr-xr-xr-x 2 root wheel schg 512 Oct 28 16:27 empty

So I checked out man chflags which says to append noschg, so i run

# chflags noschg empty/
chflags: empty/: Operation not permitted
chflags: empty/: Operation not permitted

What am I doing wrong?

If someone could point me in the right direction that would be great.

Thanks

Try running mergemaster again and don't accept any changes. At the end, when it asks you if you wish to delete /var/tmp/temproot, say "yes"

Hi,

thanks for the reply. I tried as you suggested but :

# mergemaster

*** The directory specified for the temporary root environment,
/var/tmp/temproot, exists. This can be a security risk if untrusted
users have access to the system.

Use 'd' to delete the old /var/tmp/temproot and continue
Use 't' to select a new temporary root directory
Use 'e' to exit mergemaster

Default is to use /var/tmp/temproot as is

How should I deal with this? [Use the existing /var/tmp/temproot] d

*** Deleting the old /var/tmp/temproot

rm: /var/tmp/temproot/var/empty: Operation not permitted
rm: /var/tmp/temproot/var: Directory not empty
rm: /var/tmp/temproot: Directory not empty

Any more thoughts on this?

Thanks

Try this:
cd /var/tmp/temproot/var/
chmod 777 empty
rm -rf empty

and see if that fixes it

Hi Scorpions4ever,

Thanks for the reply and suggestions. Unfortunately it didn't work

# rm -rf empty/
rm: empty/: Operation not permitted

In fact, after running mergemaster I had a whole new FS hierarchy under /var/tmp

So I also tried
# cd /var/tmp/temproot

# ls
bin boot dev etc mnt proc root sbin tmp usr var

# cd ..

# rm -rf temproot/
rm: temproot/var/empty: Operation not permitted
rm: temproot/var: Directory not empty
rm: temproot/: Directory not empty

#cd temproot/

# ls -la
total 6
drwxr-xr-x 3 root wheel 512 Nov 2 11:49 .
drwxrwxrwt 4 root wheel 512 Nov 1 22:05 ..
drwxr-xr-x 3 root wheel 512 Nov 2 11:49 var

Any more ideas?

Thanks for the help

The only thing I can think of is maybe there's something under empty/ with the schg bit set. Try this:

cd /var/tmp
chflags -R noschg temproot/
rm -rf temproot/

Thanks for all your help Scorpions4ever, but unfortunately that didn't work either.

I searched the freebsd mailing lists and saw a mention of someone else having this problem but not on how to fix it.

I have posted to the freebsd-questions mailing list and will let you know the outcome.

Well,

It turns out I had kern_securelevel="0" set in my rc.conf which was preventing me from deleting this folder <D'oh>

Thanks for all the help.
